If we increase the limit to 50 and these 50 questions can fingerprint an individual then that will be really interesting. Some hard problems :- 1. Distinguish twins 2. Using characters in names as some like Chinese use non-ascii names.

You could distinguish twins by first identifying the twins, then by asking which one's name starts earlier in the alphabet, or whatever analogue exists in languages without an alphabet. Encode appropriately.
